Darwin's Barberry Control Guide

Do's and don'ts of Darwin's barberry control

Darwin's barberry


Do's

  • Plan your control program, this will save time and money in the long-run;
  • Consider the impact of your control methods on off-target species, especially if herbicides are used;
  • Ensure machinery and equipment is washed down between sites or prior to contractors leaving site;
  • Carefully time your use of herbicide for best results (see Herbicides for Darwin's Barberry Control for more information);
  • Coordinate your control program with neighbouring landholders where your weed problem crosses property boundaries;
  • Revisit and regularly inspect the site and ensure follow-up is undertaken;
  • Use a combination of different control methods; and
  • Establish vigorous pasture (or native species) after removal to reduce re-infestation.

Don'ts

  • Don't introduce Darwin's barberry to Darwin's barberry-free areas (e.g. by failing to wash down machinery and equipment between sites);
  • Don't start your control program without first planning your approach;
  • Don't allow Darwin's barberry to flower and set seed before treatment;
  • Don't rely on one attempt at removal - follow-up is essential;
  • Don't rely on just one control method.


Spread of datura

  • Darwin's barberry spreads by birds consuming the ripe fruit and disseminating the seed.
  • Seed can also be spread via the ornamental plant trade and dumping of garden waste.
  • Seed is thought to be long-lived leading to a persistent seed bank in the soil.

Physical removal

  • Darwin's barberry plants can be cut down and the root system dug up by hand or mechanically.
  • However, plants can regenerate from suckers and follow-up control with herbicide is necessary to prevent re-establishment.

Chemical control

  • Several herbicides can be used for the control of Darwin's barberry in Tasmania in accordance with DPIPWE's off-label permit PER8949. See Herbicides for Darwin's Barberry Control for more information.
